Remote Commands of the 1xEV-DO BTS Analyzer Option (K84) R&S FSL
1300.2519.12 6.666 E-11
Characteristics
RST value: -
SCPI: device–specific
Mode
EVDO
Code Domain Power
The command returns three values for every code in a channel in the following order:
<code number>,<absolute level | relative level >,< power ID>, ...
Return values
Value Description Range Unit
<code number> code number of the channel {0…spreading
factor-1}
<absolute level> Absolute level of the code channel at the
selected channel slot
{–

...

}
dBm
<relative level> relative level of the channel referenced to total
power in the channel type
{–

...

}
dB
<power ID> Power indication
0 – inactive channel, 1 – active channel
{0,1}
The number of codes that are displayed corresponds to the spreading factor. The spreading
factor in turn depends on the selected channel types. Therefore, 32 value triplets are returned
for PILOT and PREAMBLE channels, 16 value triplets for DATA channels and 64 value triplets
for MAC channels (see Characteristics of the 1xEV-DO channel types on page 6.664).
In addition, the output depends on the mapping settings. The output is either the I branch, the Q
branch or the complex signal. If Code Domain Overview is activated, trace 1 shows the I branch
and trace 2 shows the Q branch by default.
General Results / Channel Results
The command returns 30 values selected channel in the following order::
<FERRor>, <FERPpm>, <CERRor>, <TFRame>, <RHOPilot>, <RHO1>, <RHO2>, <PPILot>,
<PMAC>, <PDATa>, <PPReamble>, <MACCuracy>,<DMTYpe>, <MACTive>, <DACTive>,
<PLENGth>, <RHO>, <PCDerror> , <IQIMbalance>, <IQOFfset>, <SRATe>, <CHANnel>,
<SFACtor> <TOFFset>, <POFFset>, <CDPRelative>, <CDPabsolute>, <EVMRms>,
<EVMPeak>, <MTYPe>
Return values
Value Description Range Unit
<FERRor> Frequency error in Hz Hz
<FERPpm> Frequency error in ppm ppm
<CERRor> Chip rate error in ppm ppm
<TFRame> Trigger to frame
Note: The Trigger to Frame value (TFRame)
supplies a '9' if the trigger is at FREE RUN.The
Timing/Phase Offset values (TOFFset/
POFFset) supply a '9' if timing and phase
measurement is disabled (refer to CDP:TPM)
or the number of active channels is higher than
50
<RHOPilot> RHO over all slots for the pilot area
